When the volume of a given mass of gas is halved and its temperature doubled, the pressure

A.

remains constant

B.

increases by a factor of 4

C.

increases by a factor of 3

D.

decreases by a factor of 4

Correct answer is B

\(\frac{P_1V_1}{T_1}\) = \(\frac{P_2V_2}{T_2}\)

V1 = 2V2 and T2 = 2T1

\(\frac{P_1\times 2V_2}{T_1}\) = \(\frac{P_2\times V_2}{2T_1}\)


P2 = 4P1
